Abstract

An active bidirectional splitter (212) for transmission and reception of data signals over a single ended transmission medium (105) comprises an input port (150), an output port (152) and a differential combined input/output port (151), a first differential output driver (115) for receiving an input signal (144) from the input port (150) and transmitting this signal to the differential input/output port (151), a second differential output driver (116) for receiving the input signal (144) from the input port (150), a first averaging circuit (121) for averaging the differential signal (146, 147) at the differential input/output port (151), a second averaging circuit (120) for averaging the differential signal (144, 145) at the output of the second differential output driver (116), and a receiver (117) for receiving both averaged signals (118, 119) from the first averaging circuit (121) and the second averaging circuit (120) and for generating therefrom an output signal on the output port (152).
